In this video, Tan Le, president of Emotiv Systems, demos the company’s computer-controller that uses brainwaves, thoughts, to direct actions on a computer. Her test subject is renowned AI researcher Marvin Minsky. The real action starts at 10:35, and I have to admit, it was pretty thrilling to see Marvin rotate that cube with his mind. Their first real-world application is purported to be game controlling.
BTW: The Emotiv headset is shown on their website as being for sale, for $300, but is currently “sold out” and said to be available in May.
